Answer:
The proportion would be 0.1
Step-by-step explanation:
Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,
![f(t) = 0.9 - 0.4\ln(t)](https://tex.z-dn.net/?f=f%28t%29%20%3D%200.9%20-%200.4%5Cln%28t%29)
If t = 7 minutes,
![f(7) = 0.9 - 0.4\ln(7)=0.9 - 0.77836=0.12164\approx 0.1](https://tex.z-dn.net/?f=f%287%29%20%3D%200.9%20-%200.4%5Cln%287%29%3D0.9%20-%200.77836%3D0.12164%5Capprox%200.1)
Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )
Not A because regular means all sides are equal.
B has to be the answer because the others are not.
Not C because a right triangle is not regular, i.e. and equilateral triangle.
Not D because a rectangle has different side lengths.
Answer:
What's confusing ??? You literally just put a dot on the number line

The number of girls is 9 :) you add the two ratio numbers to equal 5 you then divide the 15 children by the ratio of 5, which is 3. you then times 2x3 and 3x3 to get the boy and the girls numbers which are 6 &9 so the number of girls is 9
